  title: Stytch TOTP Authenticator Enrollment
  summary: Create a user, register a TOTP authenticator, and authenticate the first code.
  description: >-
    An authenticator-app (TOTP) enrollment flow for consumer apps. The workflow
    creates a user, generates a TOTP secret and QR code for that user to scan
    into their authenticator app, and then authenticates the first generated
    TOTP code to confirm enrollment and mint a session. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description. All calls authenticate with HTTP Basic auth
    using your Stytch project_id as the username and secret as the password.
